FreeBSD p04/p10 setup slower than single Linux p09 for some reason
Apache/Network seems same
From office to DC same performance on requesting small static file: ab -n 100 -c 5 http://srv/robots.txt
On each server same performance requesting a smallish text file from localhost on each machine itself : (ab -n 100 -c 5 http://dev.lan/100k.txt)
[dev-lin] Requests per second: 1821.00
[p04-bsd] Requests per second: 1113.86
[p09-lin] Requests per second: 1197.81
PG Bench – p10 is much faster
pg_bench from p04 shows the p10 Freebsd db server is much faster at network queries than the p09 Linux server
Basic standalone PHP test – p04 (FreeBSD) is much faster
office -> p09 10.3 per second - ab -n 10 -c 5 http://srv/test-pg.php?dbhost=localhost
p09 local 14 per second ab -n 10 -c 5 http://srv/test-pg.php?dbhost=localhost
p04->p09 13 per second
p04 local 80 per second!!
Full Complex Page – p09 faster
ab -n 10 -c 5 http://srv/full.php
p09 local – 2.89 per second
p04 local – 2.72 per second
Full Home Page – p09 faster
ab -n 10 -c 5 http://srv/
p04 local 1.54 per second
p09 local 2.4 per second
p09 local 2.6 per second (no open_basedir)
p04 local no openbasedir 3.88 per second
During long stress tests, with open_basedir enabled p04 at 15/85%CPU
whilst p10 is at just 6/1% CPU (user/sys)
p04 apache taking 27m / p10 pg taking 40m
p09 apache takes 29m / pg takes 26m
Tried changing accept, php settings, disabling modules etc but no effect.
BUT openbasedir did it!! Went to 3.88 per second.
So there you have it: on FreeBSD, “openbasedir” will kill your PHP performance for a complex PHP application. Disable it, and you’ll be 50% faster than Linux in this case (caveat: not a like for like comparison as the servers in this test are differently spec’d and in fact my tests elsewhere show Linux is generally faster for my uses especially if building from source).
